Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2021The c.4217C>T (p.P1406L) alteration is located in exon 50 (coding exon 50) of the COL24A1 gene. This alteration results from a C to T substitution at nucleotide position 4217, causing the proline (P) at amino acid position 1406 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
